{"id":"CVE-2026-47741","summary":"Shopper: Race condition on Discount.usage_limit allows silent over-redemption","details":"Shopper is a Headless e-commerce Admin Panel. Prior to 2.8.0, CreateOrderFromCartAction::execute previously created the Order row before checking and incrementing the discount's total_use counter. Under concurrent checkout pressure (Black Friday, flash sale, viral coupon), the global usage_limit was silently exceeded: orders were committed with the discount fully applied to price_amount while the counter blocked at usage_limit. The merchant had no signal that an over-redemption had occurred. This vulnerability is fixed in 2.8.0.","aliases":["GHSA-9rh9-hf3w-9fgg"],"modified":"2026-07-08T08:12:34.932074517Z","published":"2026-05-29T18:02:13.168Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47741.json","cwe_ids":["CWE-362"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47741.json"},{"type":"ADVISORY","url":"https://github.com/shopperlabs/shopper/security/advisories/GHSA-9rh9-hf3w-9fgg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47741"},{"type":"REPORT","url":"https://github.com/shopperlabs/shopper/issues/510"},{"type":"FIX","url":"https://github.com/shopperlabs/shopper/pull/511"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/shopperlabs/shopper","events":[{"introduced":"0"},{"fixed":"fcd0c5920588702df5b874f432b1042abd77a50b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.8.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.0","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.3","v2.3.2","v2.3.1","v2.3","v2.2.7","v2.2.6","v2.2.5","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.2","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v2.0.0-beta21","v2.0.0-beta20","v2.0.0-beta19","v2.0.0-beta18","v2.0.0-beta17","v2.0.0-beta16","v2.0.0-beta15","v2.0.0-beta14","v2.0.0-beta13","v2.0.0-beta12","v2.0.0-beta11","v2.0.0-beta10","v2.0.0-beta9","v2.0.0-beta8","v2.0.0-beta7","v2.0.0-beta6","v2.0.0-beta5","v2.0.0-beta4","v2.0.0-beta3","v2.0.0-beta2","v2.0.0-beta","v1.1.2","v1.1.1","v1.1","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","V1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.19","v0.0.18","v0.0.17","v0.0.16","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47741.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
